On the formation of seven-membered rings by arene-ynamide cyclization

ABSTRACT: A Brønsted acid-catalyzed selective arene-ynamide cyclization is described. This reaction proceeds via a keteniminium intermediate and enables the preparation of seven-membered ring enamide products. Mechanistic studies uncover an unusual product inhibition behavior. GRAPHICAL ABSTRACT: [I...
